SPECIFICATION forming part of Letters Patent No. 651,753, dated J' une 12, 1900.

Application filed February 24,1900. Serial No. 6,375. (No specimens.)

To @ZZ whom, t muy concern:

Be it known that I, BENJAMIN COBB FOWLKES, a citizen of the United States, residing at Mobile, in the county of Mobile and State of Alabama, have invented a new and useful Dental Compound,of which the follow- Y ing is a specification.

This invention relates to a dental compound wliich is termed vulco aluminium, and the object of the same is to produce a preparation or combination of ingredients or constituents capable of forming a polished metallic finish to the palatine surface and alveolar ridge of artilicial dentures made of vulcanite, commonly known as rubber plates.

The invention consists in the combination of elements or ingredients hereinafter more fully referred to and in about the proportions stated, though it will be understood thatv the proportions may be varied at will to aecommodate various applications or conditions.

The compound` consists of carbon disuld, two ounces; benzin, one dram; chloroform, one dram; powdered aluminium, one and one-half ounces; rubber, (black dental,) oneeighth of an ounce.

. In preparing the compound the rubber is first placed in the carbon disullid and a period of time permitted to elapse until the rubber shall have become thoroughly dissolved. The chloroform is then added,then the benzin, and finally the powdered aluminium, the whole combination being thoroughly shaken or agitated before using, so as to intermingle the several ingredients.

In the accompanying drawings a perspective view of a dental plate is shown by Figure l, and Fig. 2 illustrates a section through the latter.

After the cast has been prepared for packing it is varnished with shellac or any other suitable varnish, and after the said varnish has dried the cast is carefully painted with the compound or vulco aluminium, using a camels-hair brush for this operation. The cast will then have the appearance indicated by the letter A, as shown iii the accompanying drawings, and after the lirst`coat has when removed the plates need no polishing,

the latter operation usually requiring about fifteen or twenty minutes in its accomplishment. The polished metallic surface that results is particularly agreeable to the soft tissues of the mou th, and the coverin g of the compound renders the plate non-irritating to the mucous membrane of the oral cavity and prevents what is commonly known as rubber poison, nearly always found in mouths where a plain rubber plate has been worn any length of. time.

The plate treated with the compound is thoroughly aseptic and does not absorb the fluids of the mouth, as does the plain rubber, and, moreover, the plate in this form is more easily cleansed than a gold plate, and additional strength is given the plate, which will obstruct readiness to fracture. The treatment of the plate as set forth will make it perfectly adapt itself to all the rugae, undercuts of the process, depressions, and minute crevices, which is impossible in the use of a swaged orcast aluminium plate or any other metal denture. Furthermore, the plate thus treated is rendered more durable and bene-V fcial by reason of the fact that the compound is insoluble in either acids or alkalies found in the secretions of the oral cavity or any that could be tolerated in the oral cavitysuch, for instance, as are administered in medicines.
